1: How difficult is it to remove Nu-Glaze® once fitted and cured?
A: It is Extremely difficult to do so without breaking the glass. This is an excellent security feature of the Nu-Glaze® system. This is assuming the Nu-Glaze® profile has been installed with the correct amount and placement of silicone.
2: Can I use Nu-Glaze® on my very old style steel windows (old frame profiles)?
A: Yes, you can! In preparation of the frame try and ensure that the surface is flat, perpendicular to the glass. Some of the old frames have a recess area that allowed for more putty to “grip”. If necessary, use an automotive body-filler to fill the shallow recess. Alternatively, if you start removing the putty and you see there is a recess, try to retain the putty in the recess area and only remove what is necessary. It is highly recommended that the rebate offers a 90 degree, clean, intact surface to enable the silicone to seat and cure properly.
3: Do I need to remove the glass and all the putty, even though the inside putty is still perfect?
A: No, you can remove only the outer putty and then silicone the triangular outer section of Nu-Glaze® that can easily be torn or broken off on the score line provided.
4: The upright L-section (also called the toe) of Nu-Glaze® is 13mm wide, what if my frame rebate is only 10mm wide?
A: There is another score line provided to enable you to tear/break off the top 3mm if the frame rebate only allows for 10mm.
5: Are there any additional uses for Nu-Glaze®?
A: Yes, if the outer section of your profile has been torn or broken off, it is perfect to be used as a neat “quarter round”. It can be used in kitchens or bathrooms where wet conditions require a water and mold resistant material to neatly finish 90 degree corners. The hollow section underneath can even be used as trunking for thin wires or pipes, etc. Nu-Glaze® can be used anywhere where a panel - wood, glass, board, acrylic, metal, plastic or anything else -needs to be secured into a frame of some sorts or even on a flat surface.
6: Can I use any type of silicone or adhesive?
A: Nu-Glaze® Neutral cure silicone has been chosen and tested to yielded the best results – especially in terms of the reaction between the silicone and the frame material. Neutral cure has a low odour, is quick curing and has very strong bonding features as well as being highly UV resistant. If you use any other type of adhesive, we cannot guarantee the same results as experienced thus far. Furthermore, some adhesives may contain chemicals that may be harmful to PVC, causing material failure.
7: What can I use to paint Nu-Glaze® if I want to?
A: Preferably use a PVC primer to start. In preparation give the surface a slight key with some very fine grit sanding paper. When completely dry and dust free, you can re-paint with any paint of your choice. We have experienced the best results with acrylic based paints.
8: How do I measure to make sure that I have sufficient material?
A: Most windows are rectangular or square, measure the length and then the width, times each by two and add 50mm per corner to allow for the cutting of the miters. Round up rather than down to avoid having too little material. Nu-Glaze® comes in 2,0m lengths or 4,0m lengths.
9: What if the glass breaks?
A: It is relatively easy to remove the beading once the glass has been removed by pulling and removing the remaining shards and pieces. Cut the silicone while simultaneously lifting the beading off and away from the frame. This is not possible with the glass intact.
By doing this slowly, the beading can be removed in one piece, and properly cleaned of residual silicone. New glass can then be inserted and the beading can be used again. Nu-Glaze® thereby provides an added security measure for the homeowner. Putty and wooden beading strips are relatively easy to remove with the glass still intact to offer easy access for burglars and the likes.
10: What if the gasket or beading discolours over a long period of time?
A: After being primed they can easily be painted in any colour. We have experienced the best results with acrylic based paints.
11: What if someone or something breaks the surface facing to the outside?
A: Due to the double exterior wall, it will have to be a reasonably hard blow to cause a break and subsequent loss of grip of the glass. Such a hard blow will probably break the glass as well. But in the case of just the outer wall being penetrated or damaged, the inner structure and the silicone will still hold the glass in place. To repair, plastic welding can be successfully used to fix the damage.
12: Can I order Nu-Glaze® in lengths that will suit my specifications?
A: Yes, provided that a minimum order quantity is fulfilled.
13: Would Nu-Glaze® be strong enough to hold the glass and beading in place for a number of years?
A: Absolutely, a 25 year tests run in the Arizona desert has shown Silicone as the only adhesive that does not lose its original strength and toughness. Nu-Glaze® is a top quality, construction grade silicone made in Germany and has easily passed our own 5 year tests. Recently we had our system tested against SANS 613 specifications and needless to say, it passed the criteria set for residential housing standards by far.
14: Can I use any miter box?
A: Yes it is possible to do so, although we have designed and patented a specially shaped miter tool, called the Miter Buddy with 45, 50 and 60 degree markings bringing you the best results. Budget wise, you can get away with just a 45 degree Miter tool. Our patented Miter Buddy will ensure accurate cutting and is very handy as it holds the profile in place while you do the cutting.
15: Where and how can I buy Nu-Glaze®?
A: We are still in negotiation with various DIY retailers and retail groups to offer many buying solutions in the near future. Currently you can order through our website and your order will deliver to you directly. Our head office is in Cape Town.
